The dermatophyte Trichophyton schoenleinii elaborates an extracellular collagenase which is specific for native collagen and gelatin and is separable from an enzyme which is active against Azocoll. The fungal enzyme differs from the bacterial collagenases in its acid pH and small molecular weight. In addition, the fungal enzyme is irreversibly inhibited by ethylenediaminetetraacetic acid, where...

Tinea capitis is seldom caused by Trichophyton rubrum. A case is reported in a young British child and the literature reviewed.

Introduction: Tinea capitis is an infection caused by dermatophytes which have a particular affinity for keratin. Its prevalence decreased significantly in developed countries due to the improvement of sanitary conditions and socioeconomic level. However, they are still common in developing countries including Tunisia. The aim of our study was to evaluate the epidemiological, clinical and mycol...

Trichophyton rubrum is the most common agent of dermatophytosis, a disease that affects millions of individuals worldwide. Its molecular pathogenicity mechanisms are still not completely elucidated. It has been widely recognized that proteases secreted by T. rubrum are the key virulence factors during host infection. However, our knowledge about the expression of its secreted proteases in host ...

Dear Editor, Tinea barbae is a dermatophyte infection that affects primarily the bearded areas of the face.1 Sycosis is one type of clinical manifestation associated with deep folliculitis. The infection is usually caused by zoophilic fungi acquired after contact with animals.2 The presence of anthropophilic fungi, such as Trichophyton rubrum (T. rubrum), has recently been reported, and they of...
